Ricky Williams officially apologized to Dolphins fans for his abrupt retirement before last season that left the Dolphins reeling, eventually leading to a dismal 4-12 finish. ''There were things about life that I wanted to explore outside of football, and I had never had the chance,'' Williams said. ``I realize by making that decision I affected the team in a negative way and upset a lot of fans. I'm very regretful that people were hurt in the process of me doing that.'' ``I do realize that to a lot of people it comes off as being very selfish. So I do offer an apology to all the people who were negatively impacted.''
